The TJNAF Hall A Moeller polarimeter

Conference ·
OSTI ID:799172
As part of the spin physics program at Jefferson Lab, a Moeller polarimeter is being developed to measure the polarization of electron beams of energies 0.8 to 6 GeV. The device uses electron-electron scattering in a set-up in which the polarized beam is scattered from a polarized electron target. A unique signature for Moeller scattering is obtained using a series of three quadrupole magnets which provide angular selection, and a dipole magnet for energy analysis. Here, the design and commissioning of this polarimeter will be discussed along with future plans to use its small scattering angle capabilities to investigate physics in the very low q2 regime.
